Sets rock hard for a solid strong bond
Bought this epoxy adhesive to glue magnets onto my front door letterbox which was rattling during recent high winds. The magnets, now securely in place, allow a firm grip of the outer flap without the postman noticing the additional effort required in lifting the flap for mail. The epoxy resin fixes metal to metal and is completely cured within 12-18 hours. I had to take care that only the magnets were glued to the metal parts of the letterbox as any overspill would have resulted in the letterbox being totally sealed as this resin sets rock solid.

Have Patience
This stuff is really good. I was a bit dubious at first as it’s quite loose when it comes out of the syringe and stays the same on application which, to be fair, helped me out. It stayed sticky for hours afterwards causing me to think it isn’t set properly or my mix want correct. However after leaving it overnight it solidified into a really strong bond which hasn’t budged since. For reference I used it to repair a broken weld on a bar stool frame.

Worked fine - did the job I wanted
Use to repair / plug hole in lawn mower deck. The deck of the law mower had rusted through in places and I used this as a metal filler to plug the holes after I cleaned them up. Seem to have done the job.

Best adhesive I have tried.
I have now used this adhesive several times especially for cutlery used in a dishwasher. It is excellent and so far I have had no repaired items fail the dishwasher test!

It works, but it's not quick set, so bare that in mind.
I was wary with this product as I usually use Devcon, but that carries a premium price now, so I gave this a go. It mixes easily if not a tad too wet, but given time it thickens and sets. Setting time is best left overnight, but I can't knock it. Has worked well, and has proven to be sandable. Nothing gets 10/10, but this is a solid 9/10. I used it btw on a model with 50 yr old plastic, and on mounting ski bindings.

This epoxy is perfect. I use it to weld pinbacks to enamel pins. It's so sturdy. Even with the expensive shipping to the Netherlands worth every penny.

Aaaalso, dieser 2K kleber, hat in vielen Situation haufenweise Geld erspart, Beschreibung beachten und auch so umsetzen, 1 zu 1 mischen bis es schön grau wird, auftragen/einschmieren, wenn nötig nachbearbeiten, wenn man mit der Arbeit selbst fertig ist, lasst es am besten, im TROCKENEN und +15°C bereich trocknen. Es ist kein Sekundenkleber. Wenn es trocken ist, kann man nachschleifen, je nach bedarf bearbeiten. Besseres als das, habe ich bis jetzt noch nie gesehen. Sehr Gut für Heimwerker bis Bastler, sogar Handwerker.
